Commendable

I have recently taken up the hobby of 3D printing. I have experienced many issues, but not one that I could not solve such as this yet. I have a heating block that has a hole for a thermistor that is threaded in M4. My thermistor is threaded in M3. I have searched the internet for some sort of thread adapter that I could screw my thermistor into, then screw into the heating block, but I have had no success. I have also tried to just stick it in with a mixture of thermal paste and super glue, but it also was unsuccessful. If anybody could shine some light on my situation, that would be amazing!

Could you link us a few pictures or perhaps the product page of your printer, or better the heater assembly itself.

My printer uses a Chimera hotend with E3D V6 parts. The thermister is a cartridge style. It slides into the heater block and is held in place with a grub screw. The cartridge itself is potted with resin. I don't know what the max temp is for it.

The way you have worded it sounds like you too have a cartridge style thermistor. I only know of 2 types of mounting solutions but I think I've found your style on the web. I would love to help more but again more information is needed.\

The solution I can think of right now with the information I have is to either purchase an M3 thermistor of the same electrical properties as the one you have. Or turn down the M4 screw on a lathe and rethread it for M3.
